IMPROVEMENT IN AUTOMATIC FANS.

Specification forming part of Letters Patent No. 180,337, dated July 25,1876; application filed April 4, 1876.

To all whom it may concern:

Be it known that I, LAURA ETTA HAACK, of the city and county of St.Louis, and State of Missouri, have invented a new and Improved AutomaticFan; -and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the accompanyingdrawing, forming part of this specification, in which Figure l is a sideelevation; Fig. 2, a detail of the mechanism "operatin g the fan.

The object of my invention is to provide an improved automatic fanadapted to be placed above a bed or crib for the purpose of producing achange of air, and for drivingaway flies and other troublesome insects.The device is especially adapted for use in the sick-room for thebenefit of the invalid, but'is useful generally in all hot, sultrylocalities for producing a refreshing breeze for the sleeper.

The invention consists of a spring with a gearing of spur-wheels,contained in a box or suitable frame, and operating a hanging fan, thesaid box being located in a convenient position above the bed, andsupported in a detachable and peculiarly-constructed frame, whichconsists of legs, having at the bottom forked feet, which fit upon thehead and foot board, and having at the top tenons, which fit. intosockets attached to the box.

In the drawing, A represents a bed of ordinary construction, to which myimproved automatic fan is shown applied. B is a box, constructed in alight, but strong and durable, manner, and suitably ornamented, so as topresent a finished appearance. Inside this box is arranged a fra-me,carrying a spring, 0, and a set of spur-wheels, D, arranged after themanner of a clock-gearing, which operate through a worm upona fly, foran escapement to regulate the speed, which may be varied by turning thevanes of the fly, so as to alter their plane in passing throughthe air.Upon the shaft of one of the spur-wheels a is arranged a crank, b, whichis'connected with a second crank, c, by a rod, d. This latter crank c islarger than crank 11, so that it does not revolve, but simply rocks ashaft, 0, to which vided with extensions 9, having sockets.

the fan f is attached. When, therefore, the

'spring is wound up by means of a key fitting upon the main shaft, thefan, which hangs above the occupant of the bed, is moved back and forth,producing a refreshing breeze, and efl'ectually driving away all flies,mosquitoes, or other troublesome insects.

The box containing the mechanism is slotted at its bottom to allow thestem of the fan sufficient room to work, and the base is pro- In thesesockets are detachably fitted the tenons of the supporting-legs D, whichare four in number, and rest two upon the head-board and two upon thefoot-board of the bed. These supporting-legs are preferably of anornamental character, and have forked feet h,

which fit upon opposite sides of the head and foot board, so astomaintain the fan and its operating mechanism in an elevated position.These feet rest freely upon the upper edges of 'the head and foot board,and should be padded upon the inside,'so as to prevent scratching of thevarnish and disfiguring the woodwork.

I The fan, as thus described, may be regulated to run at any speed, and,by making the legs with suitable joints, can be adjusted in position soas to be near the occupant of the bed or farther away, as is desired.

It is evident that the fan with supports, as thus described, may beequally as well located in a frame above a chair. I

Having thus described my invention, what 'I claim as new is The box B,having sockets, and carrying a spring with gear-wheels operating a fan,in

combination with the supporting-legs D, hav-' LAURA ETTA HAAoK.
